The Republic of Piratini was a short-lived state that existed in southern Brazil during the mid-19th century. It was established in 1836 by leaders of the Farroupilha Revolution, who sought independence from the Brazilian Empire. The republic was primarily located in the province of Rio Grande do Sul and aimed to promote local autonomy and address grievances related to taxation and governance. The Republic of Piratini lasted until 1845, when it was dissolved following a peace agreement between the rebels and the Brazilian government. Despite its brief existence, the republic is remembered for its role in the broader context of regional struggles for independence and autonomy in Brazil, influencing future movements in the country.
